Respuesta :
The haploid number is half of the genome chromosomes of the organism, in thus case it would be 6.
The prefix di- (as seen in the word diploid) means that it is 2 (aka double) of haploid. All you have to do is divide 12 by 2
12/2 = 6
If an organism's diploid number is 12, its haploid number is 6
Hope this helped!
